Abstract: The present disclosure provides a vibration motor, including a housing with an accommodation space; a vibration part and a stator contained in the accommodation space; an elastic support suspending and supporting the vibration part in the accommodation space for providing elastic restoring force to the vibration part. The elastic support includes a first fixed part fixed on the vibration part, an elastic arm with one end thereof connected to the first fixed part, and a second fixed part formed by bending another end of the elastic arm and fixed on the housing. An extension direction of the first fixed part is perpendicular to a vibration direction of the vibration part, and an extension direction of the second fixed part is parallel to the vibration direction. Thus, the service life of the elastic support is improved.

Abstract: Disclosed are a protection method and a protection system of system partition key data and a terminal. The protection method includes: obtaining a verification table corresponding to key data carried in a system partition file when a bootloader is started, and decrypting a digital signature by using a preset public key or a private key to obtain a first verification value; generating a second verification value according to a block address and a hash value, and comparing the first verification value with the second verification value; and starting a system if the first verification value is consistent with the second verification value.
